| Product number: | QD036310 |
|---|---|
| Diameter | 460 x 570 mm |
| Type | GF/B |
- Glass fibre paper 100% borosilicate.
- Chemically inert.
- Free of binding agents.
- Depth filter.
- High carrying capacity.
- Resistant to temperatures up to 500°C.
- Structure that is as fine as a hair for strong water absorption.
GF/A:
Fine retention, smooth flow and good loading capacity. Filter for general use: filtration of water, algae-based cultures and bacteria cultures. Control of air pollution.
GF/B:
Three times thicker than GF/A, so more sturdiness and a greater loading capacity is obtained.
GF/C:
Fine retention and smooth flow. Control of potable water and natural and industrial waste. Higher loading capacity.
GF/D:
Very smooth flow and fast filtration. Thick filter with high loading capacity. Conceived as membrane front filter.
GF/F:
Excellent retention and ideal for filtration of fine parts.
934-AH:
Smooth surface and resistant to temperatures above 500°C. Environment analyses. Air and water pollution. Cell harvest. Liquid scintillation counting.
GMF 150 - 1 µm:
Multilayer filter with progressive retention of 10 µm to 1,2 µm.
GMF 150 - 2 µm:
Multilayer filter with progressive retention of 10 µm to 2,4 µm.
QM-A:
Sampling of air, acid gases, chimneys, flues and aerosols.
